Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

Field of the Invention The present invention relates to a detergent composition capable of imparting sufficient antipruritic, deodorizing and deodorizing effects to the scalp in order to sufficiently exert a bactericidal effect, and having excellent detergency and foaming power. About things.

[0002]

2. Description of the Related Art With the diversification of consumer needs, many detergent compositions having a bactericidal effect have been studied. The anionic surfactant contained as a main component in the detergent composition forms a complex with the cationic germicide, and thus often does not sufficiently exert a bactericidal effect. In addition, it is generally known that a chlorine-based germicide contained in a detergent composition has a reduced bactericidal effect due to long-term storage or storage. In order to prevent deterioration of the detergent composition without impairing the effect of the bactericide contained in the detergent composition, a stabilizer such as an antioxidant, a sequestering agent, or a clay mineral is usually added to the detergent composition. Be blended. However, a detergent composition containing these stabilizers (for example, JP-B-7-53657,
Japanese Patent Application Laid-Open No. 8-109394) suppresses a decrease in the bactericidal effect and exhibits a certain bactericidal effect, but it is not always sufficient, and the cleaning power and the foaming power are not sufficiently satisfactory.
